<meta name="abstract" content="Initiated in 1966, the North American Breeding Bird Survey (BBS) is a long-term, continental avian monitoring program designed to track the status and trends of North American bird populations.  The BBS is jointly coordinated by the USGS Patuxent Wildlife Research Center and the Canadian Wildlife Service.  Each spring during the height of the avian breeding season, participants skilled in bird identification follow a scientifically rigorous protocol to collect avian point count data on thousands of randomly established roadside survey routes throughout the continental U.S. and Canada.  These data provide an index of population abundance that can be used to estimate population trends and relative abundances at various geographic scales.">
